Halogeno alkanes

Question 1

are carbon halogen bonds polar

Answer 1

yes they are polar

Halogens are much more electronegative than carbon

Question 2

what is a nucleophile

and what do they do

Answer 2

a nucleophile is an electron pair donor
and it donates electrons to somewhere electron defficient
such as molecule with a delta positive charge

Question 3

examples of nucleophiles

Answer 3

CN- OH- NH3

Question 4

what MECHANISM involves halogenoalkanes

Answer 4

Nucleophillic substitution

Question 5

halogenoalkanes + hydroxide=

Answer 5

alcohol

Question 6

halogenoalkanes and cynaide=

Answer 6

nitrile

Question 7

halogenoalkanes+ ammonia=

Answer 7

amine

Question 8

why can amine groups keep reacting

Answer 8

this is because when they are the product in a nuclophillic substitution reaction
they have a lone pair
so they can act as a nucleophille.

Question 9

whats stronger C-F or C-I

and which reacts faster in nucleophillic substitutin

Answer 9

C-F undergo nucleophillic substitution reactions alot slower than C-I

Question 10

what mechanism occurs when halogenoalkanes are warmed up with hydroxide ions dissolved in ethanol

Answer 10

Elimination

Question 11

halogeno alkane+ OH-/water=

Answer 11

alcohol

Question 12

halogenoalkane+ Oh-/ethanol

Answer 12

alkene
