Alkene which on ozonolysis yields acetone, is
CH2=CH-CH2-CH3
CH3-CH=CH2
CH3-CH=CH-CH3
(CH3)2-C=C-(CH3)2
The addition of HBr is easiest with
CH2=CHCl
ClCH=CHCl
CH3-CH=CH2
(CH3)2C=CH2
D.
(CH3)2C=CH2
Group or atom attached with double bond bearing carbon, shows +I-effect, increases electron density on double bond bearing carbon and facilitate the attach of electrophile (hydrogen bromide) -CH3 group shows +I-effect, -Cl shows -I-effect.
The reaction
CH2 = CH2 + H2 CH3-CH3 is called
Wurtz reaction
Kolbe's reaction
Sabatier-Senderens reaction
Carbylamine reaction
