For each of the following condensed formulas, write the corresponding bond-line formula.
(i) `(CH_(3))_(2)CH(CH_(2))_(2)CH_(2)OH`
(ii) `CH_(3)(CH_(2))_(4)CHICH_(2)CHO`
(iii) `(CH_(3))_(2)CHCHCH_(3)(CH_(2))_(3)NO_(2)`
(iv) `(CN)_(2)CHCH_(2)COCl`
Strategy: In a bond-line formula, carbon and hydrogen atoms (except those that are part of the functional group) are not shown. First outline the carbon skeleton in a zig-zag fashion and show only hetero atoms and `H` atoms bonded to them.
