draw structural formulas for the following molecules:\n8. 2,2,3 - trimethyl - butane\n9. 3 - ethyl - 2,2 - dimethyl - hexane\n10. 2,3,4,5,6,7 - hexamethyl - octane

Answer

Explanation:

Step1: Analyze 2,2,3 - trimethyl - butane

Butane has 4 - carbon main chain. Two methyl groups at C - 2 and one at C - 3. $CH_3 - C(CH_3)_2 - CH(CH_3)-CH_3$

Step2: Analyze 3 - ethyl - 2,2 - dimethyl - hexane

Hexane has 6 - carbon main chain. Two methyl groups at C - 2 and an ethyl group at C - 3. $CH_3 - C(CH_3)_2 - CH(C_2H_5)-CH_2 - CH_2 - CH_3$

Step3: Analyze 2,3,4,5,6,7 - hexamethyl - octane

Octane has 8 - carbon main chain. Methyl groups at C - 2, C - 3, C - 4, C - 5, C - 6 and C - 7. $CH_3 - CH(CH_3)-CH(CH_3)-CH(CH_3)-CH(CH_3)-CH(CH_3)-CH(CH_3)-CH_3$

Answer:

  1. $CH_3 - C(CH_3)_2 - CH(CH_3)-CH_3$
  2. $CH_3 - C(CH_3)_2 - CH(C_2H_5)-CH_2 - CH_2 - CH_3$
  3. $CH_3 - CH(CH_3)-CH(CH_3)-CH(CH_3)-CH(CH_3)-CH(CH_3)-CH(CH_3)-CH_3$
