Question #4625a

Answer 1

The structure of the hydrocarbon reveals that it is saturated open chain hydrocarbon.

so its suffix name is 'ane'

It has 10 C-atoms in its longest chain. So its stem/root name is 'dec'

It has got three `CH_3-` ,methyl groups as substituent at positions 3,4,5.and one `C_2H_5-`,ethyl group at position 7.

Hence its complete IUPAC name is

7-ethyl-3,4,5-trimethyldecane

(substituents are placed as the prefixes in alphabetical order)
