why are tertiary alkyl halides more reactive in sn1?

It reacts faster in SN1 as alkyl groups are electron donating, therefore the halogen atom is more easily lost and the tertiary carbocation formed is more stable than a secondary carbocation due to the electron pushing effect of the three surrounding alkyl groups, meaning that there is more hyperconjugation and the ...

As SnCl4 show Sn 4+ oxidation state and tends to have higher positive charge and its size is smaller than Sn 2+ i.e Sn4 + polarise Cl- more than the Sn2+ ion i.e SnCl4 is covalent in nature. Hence SnCl2 is ionic whereas SnCl4 is covalent.

Tertiary alkyl halide (3o alkyl halide; tertiary haloalkane; 3o haloalkane): An alkyl halide (haloalkane) in which the halogen atom (F, Cl, Br, or I) is bonded to a tertiary carbon. Tert-butyl chloride (2-chloro-2-methylpropane), a typical tertiary alkyl halide.

As you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive.

Secondly , CH3 group in acetaldehyde decreases the positive charge on cabonyl carbon by +I effect to some extect which is not so in the case of formaldehyde, Since , Nu attack is favourable with more positive charge and less hinderance at carbonyl carbon , hence we conclude that formaldehyde is more reactive than ...

Alkanes have no pi-bonds between carbon atoms. They only have a sp3-sp3 hybridised orbital bonding (sigma bond). ... This entails more energy, so Alkanes are the least reactive among the three. This also explains why Alkynes and Alkenes undergo addition reactions, while Alkanes only undergo substitution reaction.

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.

SCH3- Since NaSCH3 is a weak base but a very strong nucleophile this means that alkyl halides undergoes an SN2 substitution rather and elimination is that right or not??

In between AlCl3 and AlF3, cation (Al) is the same both the compound. So the size of anion decides the nature of the compound. Chlorine is larger than fluorine, so the larger sized chlorine gets polarised to a greater extent by aluminium. Hence AlCl3 becomes covalent.

Alkyl halides are polar and immiscible with water. ... Alkyl halides though polar are immissible with H2O because energy is required to overcome the attractions between the haloalkane molecule and to break the hydrogen bonds between the water molecules. Thus, alkyl halides though polar are immisicible with water.

The alkyl halides are at best only slightly soluble in water. For a halogenoalkane to dissolve in water you have to break attractions between the halogenoalkane molecules (van der Waals dispersion and dipole-dipole interactions) and break the hydrogen bonds between water molecules.

The halogens all have seven electrons in their outer shells. ... As the atomic number increases, the reactivity of the halogens decreases. Fluorine and chlorine exist as gases at room temperature, while bromine is a liquid, and iodine is a solid.

Indeed, sodium amide does deprotonate terminal alkynes (it can be used for elimination reactions, too). This is possible because the NH₂¯ anion is the conjugate base of Ammonia (NH₃) and, as a general acid-base principle, the weaker the acid, the stronger its conjugate base (Conjugate acid).

The nucleophiles are almost unsolvated, so it is much easier for them to attack the substrate. Nucleophiles are more nucleophilic in aprotic solvents. So, SN2 reactions "prefer" aprotic solvents.

An Sn2 and Sn1 reaction mechanism. Sn2 reactions are bimolecular in rate of reaction and have a concerted mechanism. ... On the other hand, Sn1 reactions are unimolecular in rate of reaction and have a step-wise mechanism. This process first involves bond cleavage by the LG to generate a carbocation intermediate.

In reactions of alkyl halides (substitution( CN reactions) or elimination) the X ion will be released and will generate a strong acid(HF,HCl,HBr,HI). So the relative acidity of an alkyl halide is due to the X ion present.

1. 2. Alkyl substituents (e.g. -CH3, -CH2CH3) are also electron donating groups - they activate the aromatic ring by increasing the electron density on the ring through an inductive donating effect. This is the same effect that allows alkyl groups to stabilise simple carbocations.
