Question

(i) Write the reaction for cross aldol condensation of acetone and ethanal.

(ii) How will you carry out the following conversions:

a) Benzyl alcohol to phenyl ethanoic acid

b) Propanone to propene

c) Benzene to m-Nitroacetophenone​

Answer 1

Answer:

meta

Explanation:

c . meta position par nitro grp and oh mean phenol

Answer 2

Write the reaction for cross aldol condensation of acetone and ethanal, are listed below.

• The conversion reaction is formed by the same or different functional groups, and it is the same; it's easier to write.
• If different functional groups combine to form, it varies to the structural and functional isomer.
• According to that, the conversion reaction of ethanol to propanal needs the two methyl butane and ethylene ions.
• Two carbonyl groups, ethanol, and propanol are reacted to form four groups or products.
• Benzyl alcohol is mainly used for the inks like solvents and acidic.
• The potassium permanganate will form the benzyl alcohol.
• Propanone to propene is possible through the hydrolysis process.
• Zinc dust with phenol to get that methyl chloride to form the phenol compound.

(i)CH₃-CH₂-CH=C-CHO

                        |

                     CH₃

b) CH₃COCH₃⇒H₂, Pd CH₃CH(OH) CH₃⇒H₂SO₄ CH₃CH=CH₂

c) CH₃ COCl,  anhy AlCl₃ ⇒ COCH₃ HNO₃ ⇒H₂SO₄ COCH₃ - NO₂

Therefore, write the reaction for cross aldol condensation of acetone and ethanal, are listed above.
