Draw the structure of the following compouds:
(i) Neopentyl alcohol
(ii) trans-`2`-bromocyclopentanol
(iii) `3`-Methylhexan-`3`-ol
(iv) `4`-Phenylpentan-`2`-ol
Strategy: First write down the parent chain or ring, and then attach the `-OH` group and other sustituents to it according to their locants.

Write down structure of the following compounds: 3-buten-2-ol

Write the structure of the following compound: 3-Bromo-4 methyl hexane-2-ol

Write down structure of the following compounds: 3-bromo-2-methylpentan-2-ol

Draw the structures for the following compounds. (i) Hexa- 1,3 -dien- 5 -yne (ii) Cyclodec- 1 -en- 4 -yne (iii) 5 -Ethynyl- 1,3,6 -heptatriene Strategy: First write down the parent chain or ring. Then introduce the multiple bonds at suitable locations.

Write the structural formulae of the following alcohols : (i) But-2-en-1-ol (ii) 4, 6-Dimethylheptan-2-ol

Write the structure formulas for the following: (i) cis-Oct- 3 -ene (ii) 2,4 -Dimethylpent- 2 -ene (iii) 3,4 -Dimethylcyclopentene (iv) 1,3 -Dimethylcyclohexene (v) Vinylcyclopentane Strategy: first write down the parent C chain. Then introduce the double bond between the suitable C atoms. Finally attach the substituents and the suitable number of H atoms to satisfy the valency of C's . In cycloalkenes, one can write down the double bonds anywhere in the ring but the position of substituents is fixed by the position of double bonds.
