The cis configuration has the substituted groups on opposite side of the double bond
1 answer:
Answer:
False.
Explanation:
Hello there!
In this case, according to the attached picture, it is possible for us to evidence that cis- isomers have the substituted groups on the same side of the double bond whereas the trans- isomers have the substituted groups on the opposite side of the double bond.
In such a way, we infer that the given statement is FALSE, because that is the definition for the trans configuration.
Regards!

Explanation:
You are not providing the starting material, however, I manage to find a similar question to this, so I'm gonna use it as a basis to help you answer yours.
Now let's analyze what is happening in the reaction so we can predict the final product.
We have a ketone here, reacting at first with LDA. This is a very strong base that is commonly used in reactions with ketones and aldehydes to promove a condensation. To do this, as LDA is a strong base it will occur firts an acid base reaction, substracting the most acidic hydrogen in the molecule (Which in this case, is the Beta hydrogen of the carbonile). This will cause an enolate formation.
Then, this enolate will react with the CH3I and form a new product. The final result would be a ketone with a methyl group now attached. In the picture 2, you have the mechanism and final product.
Hope this helps
