Question

part e if you want a molecule that is highly polar, look for one that contains: c - s c - h o - n h - n s - h

Explanation:

Step1: Recall electronegativity concept

Polarity depends on electronegativity difference.

Step2: Check electronegativity values

Electronegativity values: C = 2.5, H = 2.1, O = 3.5, N = 3.0, S = 2.5.

Step3: Calculate differences

For C - S: $|2.5 - 2.5|=0$; for C - H: $|2.5 - 2.1| = 0.4$; for O - N: $|3.5 - 3.0|=0.5$; for H - N: $|3.0 - 2.1| = 0.9$; for S - H: $|2.5 - 2.1|=0.4$.

Answer:

H - N
