|
ch₃ - ch - oh
the condensed chemical structure of 1,1 - ethanediol

some facts about the 1,1 - ethanediol molecule:
number of carbon - carbon single (c - c) bonds:
number of carbon - hydrogen single (c - h) bonds:
number of oxygen - hydrogen single (o - h) bonds:
number of lone pairs:

Explanation:

Step1: Count C - C bonds

There is 1 carbon - carbon single bond in $CH_3 - CH - OH$.

Step2: Count C - H bonds

The $CH_3$ group has 3 C - H bonds and the $CH$ group has 1 C - H bond, so there are 4 carbon - hydrogen single bonds.

Step3: Count O - H bonds

There are 2 O - H bonds (from the two - OH groups).

Step4: Count lone pairs

Each oxygen atom has 2 lone pairs. Since there are 2 oxygen atoms, there are 4 lone pairs in total.

Answer:

Number of carbon - carbon single (C - C) bonds: 1
Number of carbon - hydrogen single (C - H) bonds: 4
Number of oxygen - hydrogen single (O - H) bonds: 2
Number of lone pairs: 4
