Question

Write the Lewis structure and molecular formula for each of the following hydrocarbons:

Answer 1

Answer:

molecular formula:

a) Hexane: C6H14

b) 3-methylpentane: C6H14

c) cis-3-hexene: C6H12

d)4-methyl-1-pentene: C6H12

e) 3-hexyne: C6H10

f) 4-methyl-2-pentyne: C6H10

Explanation:

structure:

a) hexane : CH3-CH2-CH2-CH2-CH2-CH3

b) 3-metilpentane: CH3-CH2-CH-CH3-CH3

                                                 CH3

c) cis-3-hexene:   CH3-CH2-CH=CH-CH2-CH3

d)4-methyl-1-pentene: CH2=CH-CH2-CH-CH3

                                                              CH3

e) 3-hexyne: CH3-CH2-C≡C-CH2-CH3

f)4-methyl-2-pentyne: CH3-C≡C-CH-CH3

                                                      CH3
