Question

WRITE A BALANCED EQUATION FOR THE COMPLETE COMBUSTION OF:

a) ETHANE
b) CYCLOHEXANE
c) PENTANE


WRITE A BALANCED EQUATION FOR EACH OF THE FOLLOWING:

a) CH2=CH-CH2-CH3+HCl --->

b) CH3-C=CH2+HBr
I
CH3

THE CH3 IS UNDER THE SINGLE CARBON IN b).

Answer 1

a) 2C2H6 + 7O2 --> 4CO2 + 6H2O

b) C6H12 + 9O2 --> 6CO2 + 6H2O

c) C5H12 + 8O2 --> 5CO2 + 6H2O

You must apply Markovnikov rule for the next addition reactions:

a) CH2=CHCH2CH3 + HCl --> CH3CH(Cl)CH2CH3

b) CH2=C(CH3)CH3 + HBr --> CH3-CBr(CH3)CH3
