Question

1. rank the bonds according to increasing electronegativity. (0.5 points) *

br - h
si - h
o - h
c - h
cl - h

1. covalent compounds are also called ______. (0.5 points) *

enter your answer

Explanation:

Step1: Find electronegativity values

Electronegativity values: \(H = 2.1\), \(Si=1.8\), \(C = 2.5\), \(Br=2.8\), \(Cl = 3.0\), \(O=3.5\).

Step2: Calculate electronegativity differences

For \(Si - H\): \(2.1-1.8 = 0.3\).
For \(C - H\): \(2.5 - 2.1=0.4\).
For \(Br - H\): \(2.8 - 2.1 = 0.7\).
For \(Cl - H\): \(3.0 - 2.1=0.9\).
For \(O - H\): \(3.5 - 2.1 = 1.4\).

Covalent compounds are formed by sharing of electrons between atoms. They are also known as molecular compounds as they exist as discrete molecules.

Answer:

\(Si - H\lt C - H\lt Br - H\lt Cl - H\lt O - H\)
