Question
20. A nucleophilic center a. is always positive b. is electron poor c. always has a double bond d. is electron rich e. cannot react 21. The types of intermolecular forces that exist between the molecules of hydrocarbons are: a. DD interactions b. H bonds c. VWF (or LDF) d. H bonds and DD interactions e. VWF and H bonds 22. Which one of the following compounds is soluble in water? a. CH3NH2 b. C6H14 c. C5H12 d. C2H6 e. C4H8 23. Which one of the following is not an alkane? a. C2H2 b. C2H6 c. C40H82 d. C4H10 e. C11H24Explanation / Answer
20. d) is electron rich
Thats why they seek electrron deficient or nucleophilic centre..
21. c) VDW or van der waal forces
( No H bonding in hydrocarbons.....because we talking about only Carbon and Hydrogen )
22. a) CH3NH2
hydrocarbons are not water soluble..... added amine group is the cause of solubility
23. a) C2H2
(Alkanes have general formula CnH2(n+1)
