Answer 2

1) 2,3-диметил-3-этилоктан:

The structural formula for 2,3-dimethyl-3-ethyloctane is as follows:

CH3   CH3
  |     |
CH3 - C - C - C - C - C - C - C - CH2 - CH3
      |       |
     CH2     CH2

This compound belongs to the class of alkanes, which are hydrocarbons with only single bonds between carbon atoms.

2) 2,2-дибромнонен-4:

The structural formula for 2,2-dibromononen-4 is as follows:

Br   Br
 |    |
CH2 - C - C - C - C - C - C - C - CH2 - CH3
     |       |
    CH2     CH2

This compound belongs to the class of haloalkanes, which are organic compounds containing halogen atoms (in this case, bromine) attached to carbon atoms.

3) 2-метилгексин-3:

The structural formula for 2-methylhexyne-3 is as follows:

CH3
  |
CH3 - C - C - C - C - C - CH3
      |       |
     CH2     CH3

This compound belongs to the class of alkynes, which are hydrocarbons that contain a triple bond between carbon atoms.
