Hi$,$ please explain how you arrived at the answer in detail. Thank you!Solve this task and please explain how you arrived at the answer. $($That is$,$ how to solve such

tasks$)$ especially with task c$)$ d$)$ and e$).$

Elacestrant is a new medicine used to treat certain types of breast cancer.

a$)$ State the functional groups with name and label.

b$)$ State stereocenters and account for the number of possible stereoisomers.

c$)$ Write down the structure of Elacestrant at the following $pH$ :

i$.pH=1$

ii$.pH=7$

iii. $pH=11$

d$)$ Explain at which of the three $pH$ that Elacestrant will be most soluble in water. $($Here it is

expected that involve intermolecular interactions of the functional groups with water$)$

To achieve a longer$-$lasting concentration of Elacestrant, you can react Elacestrant with

acetic acid,

whereby an ester is obtained as a product.

e$)$ Write down the product for the condensation of Elacestrant with acetic acid.
