Answer 1

A molecule containing only hydrogen and carbon atoms

Question 2

What is displayed formula

Answer 2

Formula which shows every atom and every bond

Question 3

What is structural formula

Answer 3

Shows unambigously how atoms are joined together
e.g CH3,CH2,CH3

Question 4

Answer 4

shows all bonds between carbon atoms

Question 5

what is molecular formula

Answer 5

Shows the actual number of atoms in each molecule

Question 6

Empirical Formula

Answer 6

Shows the number of each atom in simplest whole number ratio

Question 7

1st step of naming compounds

Answer 7

unbranched alkanes are named according to number of carbon atoms e.g meth, eth, prop, but

Question 8

2nd step of naming compounds

Answer 8

Determine the principle chain by finding the chain/route with the most carbon atoms

Question 9

3rd step of naming compounds

Answer 9

If 2 or more chains have same number of carbon atoms chose the principle chain as the one with the highest number of branches

Question 10

4th step of naming compounds

Answer 10

Number the carbon atoms of the principle chain from 1 to end with carbon atom 1 being the carbon at the first branch

Question 11

What is a structural isomer

Answer 11

compound with the same molecular formula but different structural formula.

Question 12

3 types of structural formula

Answer 12

Chain
Position
Functional Group

Question 13

what is chain isomer

Answer 13

molecule with diff carbon chain

Question 14

what is functional group isomer

Answer 14

Structural isomer that differ by functional group

Question 15

what is position isomer

Answer 15

molecule with the same functional group attached in different position

Question 16

sterioisomerism

Answer 16

molecule with the same molecular + structural formula but diff spatial arrangement of atoms

Question 17

geometricisomerism

Answer 17

type of sterioisomerism with diff arrangement of groups around c=c

Question 18

cis(Z) isomer

Answer 18

isomer where the highest priority group at each end of c=care on same side

Question 19

trans(E) isomer

Answer 19

isomer where the highest priority group at each end of c=care on different sides

Question 20

how to find whether its E or Z

Answer 20

1. Find RFM of both molecules on both sides of c=c
2. The molecule with highest RFM is priority molecule
3. If priority molecules line up on same side horizontally its Z
4. If priority molecules line up diagonally its E
