Question

Draw the structures of
A) 2-bromo-pentane
B)butanol
C)hexyne
D)2 methyl propane

Answer 1

2-
Bromo pentane.the structure of bromo pentane is some like similar to it.... But difference in structure is bromine is attached at the second carbon chain

Answer 2

A) bromo pentane:
"pent" means 5 carbons. " ane" is single bond.
draw 5 carbon atoms and satisfy with hydrogens.in the 2nd place give a bromine atom.

B)butanal,
"but" is 4 carbon atoms "al " at last means aldehyde functional group.
so draw 4 carbon atoms and satisfy it with hydrogens and also give aldehyde functional group.

C)hexyne,
"hex" means 6 carbon atoms. "yne" is triple bong
so give 6 carbons atoms and draw triple bond between one.

D)2 methyl propane:
draw 3 parent carbons first and then in the middle carbon, give a branch of one more carbon.satisfy with hydrogens.

*look at the attachments for the structure.

hope it helps!!
