MCQ
The bond angle in $s{p^2}$ hybridisation is
  • A
    ${180^o}$
  • ✓
    ${120^o}$
  • C
    ${90^o}$
  • D
    ${109^o}2'$
✓

Answer

Correct option: B.
${120^o}$
b
An $sp ^2$ hybridized atomic orbital is the mixing of $1 s$ orbital and $2 p$ orbitals, a $sp ^2$ hybridized atom has $3 \sigma$ bonds so its molecular geometry is trigonal with $120^{\circ}$ bond angles.
