Which of the following molecular geometry best describe the shape and polarity of CH₄?
|
tetrahedral polar
|
|
tetrahedral nonpolar
|
|
trigonal pyramidal non polar
|
|
trigonal pyramidal polar
|
Explanation:
Detailed explanation-1: -This is tetrahedral, and this angle is equal to 109.5 degrees and it is non polar. Did you know?
Detailed explanation-2: -Explanation: We often say that a C-H bond is nonpolar because the electronegativities of C and H are so close to each other.
Detailed explanation-3: -The molecular geometry of methane-CH4-is tetrahedral with symmetric charge distribution on the central atom. Therefore this molecule is non-polar.
Detailed explanation-4: -Methane $$( has symmetrical tetrahedral structure hence dipole moment is zero. Therefore it is non-polar.
