Question

Question 9.10 Do you expect the carbon hydrides of the type (CnH2n + 2) to act as ‘Lewis’ acid or base? Justify your answer.

Class XI Hydrogen Page 289

Answer 1

Carbidn hydrides of the type (CₙH₂ₙ+₂) are electron - precise hydrides . They have exct number of electrons required to form covalent bonds.
But we know,Lewis acids are electron deficient species and Lewis bases are electron rich species.

Hence, they neither act as Lewis acids nor Lewis bases.

Answer 2

Answer :

Carbon hydrides of the type Cn H2n+2 are electron precise hydrides. Because they have atom with exact number of electrons to form covalent bonds. Thus, they do not behave as Lewis acid or base. Since they have no tendency to accept or lose electrons.
