Question

The bond angle in methane _____.

• A. ${109}^{\circ }{31}^{\prime }$
• B. ${107}^{\circ }{48}^{\prime }$
• C. ${180}^{\circ }$
• D. ${198}^{\circ }{28}^{\prime }$

Answer 1

Answer: (A)

${109}^{\circ }{31}^{\prime }$

Methane is $s{p}^3$ hybridized. When the $s{p}^3$ hybrid orbitals are formed they arrange themselves far apart as posible. It has tetrahedral arrangement with an angle of ${109.5}^{\circ }$.
