Sample answer

CH4
Calculate Bond Pairs	C + 4H = 1(4) + 4(1) = 4 + 4 = 8 (Have) C + 4H = 1(8) + 4(2) = 8 + 8 = 16 (Need) Need Have = 16 - 8= 8 8 / 2 = 4 Bond Pairs
Calculate Lone Pairs	4 Bond Pairs x 2 = 8 Have First step = 8 8 = 0 0 / 2 = 0 Lone Pairs
Draw Lewis Structure for the Simple Molecules and Polyatomic Ions	H H C H H
VSEPR Notation	AX4
Prediction of Molecular Shapes	Tetrahedral
Polarity (Justify)	CH4 is a non-polar molecule because same surrounding elements with same EN and also No Lone pairs on Central Atom.
