In the three-dimensional structure of methane, CH4, the hydrogen atoms attached to a carbon Group of answer choices at the corners of a tetrahedron. at the corners of a square. at the corners of a rectangle. at the corners of a cube. in a straight line.

Answer : The correct option is, at the corners of a tetrahedron.

Explanation :

Formula used  :

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

Now we have to determine the hybridization of the given molecule.

The given molecule is,

The number of electron pair are 4 that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral and the bond angle will be, .

Hence, the correct option is, at the corners of a tetrahedron.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
