Which are the correct IUPAC names of the following compound?
(i) 5 – (2′, 2′–Dimethylpropyl)-decane
(ii) 4 – Butyl – 2,2– dimethylnonane
(iii) 2,2– Dimethyl – 4– pentyloctane
(iv) 5 – neo-Pentyl decane
The answer is the option (i) 5-(2’,2’-Dimethylpropyl)-decane & (iv) 5-neo-Pentyldecane
Explanation: The longest carbon chain has 10 carbon atoms, hence ‘decane’. Sidechain is present on 5th carbon atom, viz., neo-Pentyl or 2’,2’-Dimethylpropyl according to IUPAC. Hence option (i) & (iv).
