Which of the following compounds will show cis-trans isomerism?
(i) `(CH_(3))_2C=CH-C_(2)H_(5)`
(ii) `CH_(2)=CBr_(2)`
(iii) `C_(6)H_(5)CH=CH-CH_(3)`
`CH_(3)CH="CC"lCH_(3)`

Explanation

To determine which of the given compounds can exhibit cis-trans isomerism, we need to analyze each compound based on the criteria for cis-trans isomerism:

1. **Presence of a Double Bond**: Cis-trans isomerism occurs in compounds with a carbon-carbon double bond (C=C) since it restricts rotation around the bond.
2. **Different Groups Attached**: For cis-trans isomerism to occur, the groups attached to the carbon atoms involved in the double bond must be different. If the same groups are attached to both sides, cis-trans isomerism cannot occur.

Now, let's analyze each compound step by step:

### Step 1: Analyze Compound (i) `(CH₃)₂C=CH-C₂H₅`
