alkynes

Question 1

hybridization of triple bonc c

Answer 1

sp and linear geometry

Question 2

how to draw alkynes

Answer 2

must draw them linear
-NO BENDING

Question 3

terminal alkyne

Answer 3

has a proton/h connected directly to the triple bond

Question 4

internal alkyne

Answer 4

no proton/ h

Question 5

removing h from terminal alkyne/ deprotonate

Answer 5

USE A STRONG BASE
-result is a conjugate base/ alkynide ion
-the ion is a strong nu for an sn2 rxn but the substrate must be a methyl halide or primary halide

Question 6

base used to deprotonate

Answer 6

must be less stable (a stronger base) than the resulting alkynide ion
-use ario to determine stability
-nah or nanh2

Question 7

ario

Answer 7

-stability increases as you go right
-sp is more stable

Question 8

alkyne synth

Answer 8

treat a germinal dihalide or vicinal dihalide w a strong base
-requires two moles of base for every more of dihalide ex nah2
-product is an alkynide salt that gets protonated
-it is 2 e2 reactions happening

Question 9

protonate

Answer 9

take a proton and put it on the negative charage/ atom w out H

Question 10

alkylation

Answer 10

doing sn2 w ion and useing the ion as a nu
-step 1= convert alkyne to ion with nanh2 (strong base)
