Question

Consider a chemical species in which a carbon atom forms single bonds to three hydrogen atoms in which the carbon atom possesses no other valence electrons.
(a) What formal charge would the carbon atoms have?
(b) What shape would you expect this species to have?
(c) What is the hybridization of carbon atom?

Answer 1

Given 3 bonds with hydrogen & no other valence electrons

So the Formal charge is present on carbon which is $+1$. It has a triangular planer shape with $s{p}^2$ hybridization.
