Sure, you can suggest me a topic for which you need first. Though, I am going to publish a course on Stereochemistry.

Hello Dandin, the course on Stereochemistry has been published, you can go through and ask your queries. In my upcoming course I will discuss the stereochemistry in cyclobutate and cyclohexane. They are the part of IIT- JAM.
sir exa. 18 how to you find the value of y
sir in ex19. If P =32i - j -14k aye tobi sahi h n ??

awesome sir thank u
The last question (Ex.19) can be done by an easy approach....We know that vector P is perpendicular to both A & B by vector P will be mx(cross product of A & B vectors )....where m is a constant value....And then by Dot product with the vector C we can find the value of m......And we got the required vector P......No need to solve 3equations of 3 variables...Am I right sir??
mx(cross product)....x is multiplication symbol here.

bhai basically both the process are same...what you are calling as m, sir is calling it as k... just go through that...
