Draw a mechanism for this reaction. 5-hydroxypentanoic acid forms 2-oxanone in the presence of acid. draw all missing reactants
Licemer1 [7]

Answer: -

The first step involves protonation of the carbonyl oxygen.

After protonation, the Alcohol oxygen now attacks the carbon of the carbonyl.

Thus a six membered ring is formed with 5 carbon atoms and 1 oxygen atom. The 1st position carbon atom has 2 OH groups.

One of these gets again protonated.

This leaves as water. With the loss of the H+, there results a carbonyl at 1 position.

Thus 5-hydroxypentanoic acid forms a lactone or 2-oxanone in presence of acid.

Mars is 7AU from earth, what is that in mm
aniked [119]

7AU = 1 × 10^15 mm

7AU × (1.5 ×10^8 km/1 AU) = 1.0 × 10^9 km

1.0 × 10^9 km × (1000 m/1 km) = 1.0 × 10^12 m

1.0 × 10^12 m × (1000 mm/1m) = 1 × 10^15 mm
