Question “Label the boxed functional groups in the steroid molecule. 1) 2) 3) Label the boxed functional…”
Label the boxed functional groups in the steroid molecule.
1)
2)
3)
Answer
Question 1
Unfortunately, functional groups must be remembered. Below is a list of them.

Question 2
Below is the reaction scheme. The first step is to alkylate the alkyne using NaNH 2. This creates a carbon nucleophile that can attack CH 3CH 2Br. To retain the alkene, the alkyne can react with one similar with Br 2.

Question 3
The synthesis is fairly straightforward. To make alcohol, reduce the aldehyde by adding sodium borohydride. With PBr 3,, the alcohol can be made into a good-leaving group (Br). Lastly, the corresponding nitrile can be obtained by adding NaCN through SN2 substitution.
Conclusion
Above is the solution for “Label the boxed functional groups in the steroid molecule. 1) 2) 3) Label the boxed functional…“. We hope that you find a good answer and gain the knowledge about this topic of science.
