Concept explainers
a)
Interpretation:
Starting from any compound having four or less number of carbon atoms how the compound shown can be prepared is to be stated.
Concept introduction:
A cyclopropane ring is formed in Simmons-Smith reaction when an alkene is treated with CH2Cl2/Zn-Cu couple. Higher
To state:
Starting from any compound having four or less number of carbon atoms how the compound shown can be prepared.
b)
Interpretation:
Starting from any compound having four or less number of carbon atoms how the compound shown can be prepared is to be stated.
Concept introduction:
The compound shown has a keto group at C2 and a double bond between C5 & C6. The keto group can be introduced by hydration of an alkyne with aqueous H2SO4 in the presence of HgSO4. An enol obtained during hydration upon tautomerization yields the
To state:
Starting from any compound having four or less number of carbon atoms how the compound shown can be prepared.
