Question

use this condensed chemical structure to complete the table below. the condensed chemical structure of acetic anhydride some facts about the acetic anhydride molecule: number of carbon - carbon single (c - c) bonds: number of carbon - hydrogen single (c - h) bonds: number of lone pairs:

Explanation:

Step1: Count C - C single bonds

In the structure $CH_3 - C - O - C - CH_3$, there is 1 carbon - carbon single bond.

Step2: Count C - H single bonds

Each $CH_3$ group has 3 C - H single bonds. Since there are 2 $CH_3$ groups, the number of C - H single bonds is $2\times3 = 6$.

Step3: Count lone pairs

Oxygen atoms have lone pairs. Each oxygen in the $C=O$ groups has 2 lone pairs and the oxygen in the middle has 2 lone pairs. So in total, there are $2\times2 + 2= 6$ lone pairs.

Answer:

number of carbon - carbon single (C - C) bonds: 1
number of carbon - hydrogen single (C - H) bonds: 6
number of lone pairs: 6
