Q. The arrangement of hydrogen atoms around carbon in the methane molecule is
Chhattisgarh PMTChhattisgarh PMT 2005
Solution:
In methane the central atom, carbon is in a state of $s p^{3}$ hybridization. Four $s p^{3}$ hybrid orbitals around the central atom are directed tetrahedrally in a bid to be at maximum possible distance from each other. These four tetrahedrally inclined orbitals overlap with s-orbitals of four $H$-atom. The four $C-H$ bonds are mutually inclined at an angle of $109^{\circ} 28'$.
