Query: On finite CG-groups   A finite group $G$ is a CG-group if $|{\rm Cent}(G) | = | G' |+2$, where $G'$
is the commutator subgroup and Cent$(G)$ is the set of distinct element
centralizers of $G$. In this paper we give some results on CG-groups. We also
give a negative answer to \cite[Conjecture 2.3]{con} given by K. Khoramshahi
and M. Zarrin.
