Answer:

I think you gots #"3-methylpentene"#.......

Explanation:

#"3-methylpentene"#.......fits the description for #A#.

#H_3stackrel5C-CH_2-stackrel3CH(CH_3)stackrel2C=stackrel1CH_2#

We start with an olefin.......#H_2C=CHCH(CH_3)CH_2CH_3#, with a chiral centre at #C3#.

And hot permanganate will oxidize off the methylene group as carbon dioxide to give......

#H_3stackrel4C-CH_2-stackrel2CH(CH_3)CO_2H#

We have a carboxyl group at the position of the former #C_2#.

The chiral centre is the prior #C3#.
