Select all that apply:

A) Linear alkanes have the molecular formula CnH2n.

B) They have delocalized alternating carbon-carbon single and double bonds.

C) They interact though attractive van der Waals forces.

D) They contain only single bonds.

Answer 1

A) Linear alkanes have the molecular formula CnH2n.

It's NOT a characteristic of alkane. General formula of alkane is C_nH_2n+2.

B) They have delocalized alternating carbon-carbon single and double bonds.

It's NOT a characteristic of alkane. In alkane there s no C=C but there are only single bonds as C-C and C-H.

C) They interact though attractive van der Waals forces.

Yes, Alkane interact through Van der Waals forces.

D) They contain only single bonds.

Yes, there are only single bonds C-C and C-H etc.

Answer Options:: (A) & (B).
