show the products of the reaction of CH3CH2CH=CH2 with (a) HCL (b) Br2 (c) H2

Answer 1

CH3CH2CH=CH2 is 1-Butene
I'm sure google can provide you with the reactions you seek

Answer 2

I tried looking on Google with not much luck. Both Br2 and H2 add across the double bond to form CH3CH2CHBrCH2Br and CH3CH2CH2CH3. HCl adds across the double bond, also, BUT does it add CH3CH2CH2CH2Cl OR CH3CH2CHClCH3? Markonikov's rule states it is the latter; i.e., the H goes to the C atom containing MORE H atoms. You should read up on the mechanism of this addition AND which conditions favor the addition by Markonkov's rule and which conditions favor the anti-Markonkov's rule.
