Text Solution

Verified by Experts

The correct Answer is:
B
The alkane with the given carbon atom is `CH_3-undersetunderset(CH_3)|oversetoverset(CH_3)|C-CH_3` Since it has all the four H in `CH_4` substituted by `CH_3` groups . (a) is correct . Neopentane is the common name for this alkane and so, (b) is correct. The longest carbon chain consists of 3 carbon atoms and so, in the IUPAC system it is (c ). (d) is the incorrect name .
