Answer: B) Lal Bahadur Shastri Explanation:

Answer: A) nonpolar, with a symmetrical distribution of charge Explanation: CF4 is tetrahedral. Since the four 'F' atoms have the same electronegativity values, there is no bias in electron distribution toward any one.   Therefore, electron/charge distribution is symmetrical, which also means that the molecule is nonpolar.   Hence, CF4 is nonpolar molecule with a symmetrical distribution of charge.

Answer: C) Lactose Explanation: Lactose is the major carbohydrate in the milk of most species.   Lactose is a disaccharide composed of the monosaccharides D-glucose and D-galactose, joined in a ß-1,4-glycosidic linkage. The chemical name for lactose is 4-0-ß-D-galactopyranosyl-D-glucopyranose.
