Q. Aldol condensation between the following compounds followed by dehydration gives methyl vinyl ketone:

methanal and ethanol

two moles of formaldehyde

methanal and propanone

two moles of ethanal

$C H_{2} = O + C H_{3} - O ∣∣ C - C H_{3} - Alkali C H_{2} = C H - O ∣∣ C - C H_{3}$

Q. Aldol condensation between the following compounds followed by dehydration gives methyl vinyl ketone:

methanal and ethanol

two moles of formaldehyde

methanal and propanone

two moles of ethanal

CH2​=O+CH3​−O∣∣C​−CH3​− Alkali ​CH2​=CH−O∣∣C​−CH3​

$C H_{2} = O + C H_{3} - O ∣∣ C - C H_{3} - Alkali C H_{2} = C H - O ∣∣ C - C H_{3}$
