Question

Which of the following would be named with a name that ends in -ane?

CH3-CH2-CH3

CH3-CHCH-CH3

CHC-CH2-CH3

CH3-CH2-CH2-CHCH2

Answer 1

the suffix ane denotes an alkane, which is a carbon chain fully saturated with hydrogen's (No double or triple bonds).

I would recommend drawing a lewis diagram or just drawing a stick diagram showing all bonds of each compound to figure out which chain is fully saturated with hydrogens
