Question

Find the expression that can be used to designate a linear nonpoplar molecule that contains polar bonds.

• A. $H_2\left(g\right)$
• B. $C{O}_2\left(g\right)$
• C. $2N_{2}O\left(g\right)$
• D. $2NaCl\left(aq\right)$
• E. $H_{2}S{O}_4\left(aq\right)$

Answer 1

The correct option is B $C{O}_2\left(g\right)$

The expression $C{O}_2$ can be used to designate a linear nonpoplar molecule that contains polar bonds.
$O=C=O$ is linear in structure as C atom is $sp$ hybdridized.
$C=O$ bonds are polar but individual $C=O$ bond dipoles cancel each other. Due to this, the molecule is non polar.
