Y The magic of seven colours...


hellos 1C
examples 6 of tutorial 11
6) the first 3 members of a family of hydrogen(h) and carbon(c) compounds called alkenes have bonding structures below
H H H H H H H H H

C=C C=C=C C=C=C=C

H H H H H H H H H
n=1 n=2 n=3

a) Draw the structure for the 4th member of the family
b) Complete the folowing table.

n Number of Carbon atoms Number of Hydrogen atoms (table)
1
2
3
4
c) The formulae for the first three members are written as C2H4,C3H6 and C4H8 respectively . Write down a general formula for the nth member of the family.

sorry cannot post qn7 cos cannot draw out the diagrams. anyways without the diagrams you cannot do the questions...
try to bring back yr homework next time hor
sry very untidy ah...
hehe
