Organic chemistry mix

Question 1

Alcohols (butan-1-ol, butan-2-ol, 2-methylpropan-2-ol) oxidised with acidified potassium dichromate, identify products

Answer 1

Question 2

Types of alcohols

Answer 2

Question 3

How to identify which compound can exist as optical isomer?

Answer 3

Chiral C - central with 4 different domains

Question 4

Reaction of halogenoalkanes and aq NaOH

Question 5

What type of compound has min 3 C?

Answer 5

Ketone

Question 6

Determinants of Sn1/Sn2 rate

Answer 6

Sn1 - 1 determinant - 2/3 halogenalkene conc

Sn2 - 2 determinants - 1/2 halogenalkane conc + nucleophile conc

Question 7

How to identify which compound can show optical activity

Answer 7

Optical activity - bends polarised light

Question 8

What are the types of polymers?

Answer 8

• addition polymers (polyalakanes)
• condensation polymers (polyesters, proteins)

Question 9

Why Cl-C-C-C-Cl cannot be synthesised from C₂H₄?

Question 10

Incomplete conbustion of hydrocarbon products

Answer 10

CO and C

Question 11

How to dinstinguish whoch one is better LG?

Answer 11

1. The larger the ion - the better LG
2. The lower EN - the easier to leave

Question 12

Define homologous series

Answer 12

Differ by CH2 group (all alkanes are homologous

Question 13

Which will form positive ion?

CH₃CH₂CH₂Br + OH or (CH3)₃CBr + OH

Answer 13

(CH3)₃CBr because tertiary halogenalkane - Sn1 - in Sn1 carbocation - positive ion

Question 14

Orange to green in organic chem

Answer 14

Reduction of potassium dichromate

Question 15

Types of halogenalkanes

Answer 15

Question 16

C₂H₄ -> CH₃CH₂OH type of reaction

Answer 16

Hydration (addition of H₂O)

Question 17

CH₃CH₂OH -> CH₃COOH type of reaction

Answer 17

oxidation

Question 18

Functional group isomers

Answer 18

Alkanes -> alkenes/alkynes/halogenalkanes/cycloalkanes/alcohols

alkenes -> alkynes

Alcohols -> ethers

Carboxylic acid -> esters
