Question

Q: How many of the molecules shown contain only one covalent bond?

Answer 1

Answer:

cl2 - 1 bond

HCl.- 1 bond

N2 - 3 bond

o2 - 2 bond

• Cl requires one electron to complete it's octave so it share it's one electron with other chlorine and make a single covalent bond
• H has one electron and Cl requires one so both form one single bond
• N requires 3 electrons so it form 3 bonds with other N
• oxygen requires 2 electrons so it forms 2 bond with other oxygen
