rate propto (1/ text steric crowding of aldehyde ) t-butanol can show formation of carbocation in acidic medium.

Q. In the following reaction
Aldehyde + Alcohol $H C ℓ$ Acetal
Aldehyde Alcohol
$H C H O^{t} B u O H$
$C H_{3} C H OM e O H$
The best combinations is :

$H C H O$ and $M e O H$

HCHO and $^{t} B u O H$

$C H_{3} C H O$ and MeOH

$C H_{3} C H O$ and $^{t} B u O H$

rate $\propto \frac{1}{steric crowding of aldehyde}$
t-butanol can show formation of carbocation in acidic medium.
