Haloalkanes and Alkynes

Question 1

Primary haloalkanes

Answer 1

-X is attached to a C bonded to 1 other C

Question 2

secondary Haloalkanes

Answer 2

-X is attached to a C bonded to 2 other C’s

Question 3

tertiary haloalkanes

Answer 3

-X is attached to a C bonded to 3 other C’s

Question 4

how are C atoms numbered in a haloalkane

Answer 4

C atoms are numbered to give the smallest number to halogens and the halogen atom prefix’s are arranged alphabetically so Bromo is on the smaller number C than chloro

Question 5

Substitution reactions of haloalkanes equation

Answer 5

haloalkane +KOH (aq) arrow alcohol

haloalkane + NH3 (alc) arrow amine

Question 6

elimination reactions of Haloalkanes

Answer 6

the halogen atom and a hydrogen atom from an adjacent C atom is removed resulting in an alkene

Question 7

elimination reaction of haloalkanes equation

Answer 7

haloalkane arrow (KOH (alc) alkene

Question 8

saytzeff’s rule

Answer 8

determines which will be the major product. an H is removed from the adjacent C with the fewest attached H’s

Question 9

properties of alkynes

Answer 9

similar physical properties to alkanes and alkenes and undergo addition reactions like alkenes

Question 10

addition reactions with Alkynes

Answer 10

occur in 2 steps (from triple bond to double bond to single bond)
