Solution

Cross aldol condensations basically the reaction between carbonyl reactants which are different.
Cross added products of $e t h a n a l + p r o p a n a l :$
$∙ 2 - m e t h y l b u t - 2 - e n a l; C H_{3} - C H = C - C H_{3} - C H O$
$∙ P e n t - 2 - e n a l; C H_{3} - C H_{2} - C H = C H - C H O$
$∙ B u t - 2 - e n a l; C H_{3} C H = C H = C H - C H O$
$∙ 2 - m e t h y l p e n t - 2 - e n a l; C H_{3} C H_{2} C H = C - C H_{3} C H O$
