9.1o  Do you expect the carbon hydrides of the type (CnH2n + 2) to act as ‘Lewis’ acid or base? Justify your answer.

the general term  C_{n}H_{2n+2}

for n = 1, 2, 3.. we get   CH_{4},C_{2}H_{6},C_{3}H_{8}...

Lewis acids are an electron acceptor, So the above compound should be electron deficient species.

C_{2}H_{6}  taking an example

Here we can directly count that both the Carbon atom has perfect 8 electrons in sharing. they follow the octet rule. It is electron precise hydride and it neither donate or accept electrons to act Lewis acid or base
