Question

How many single bonds are in a hexane molecule?

Answer 1

By my count there are `19` `C-C`, and `C-H` bonds.

Explanation:

Draw out the molecule, `H_3C-CH_2CH_2CH_2CH_2CH_3`, and count the `C-H`, and `C-C` bonds. There are `5` `C-C` bonds, and `14` `C-H` bonds. Of course, there are different isomeric structures available, but for an alkane, there are no degrees of unsaturation.
