how to describe it is written already

Sorry, I actually never came across such a question, so wanted to confirm.
I don't really know how to describe, but check this, you might find what you need.

Dehydration reactions aren't electrophilic, they're elimination reactions, and, like with hydration, have their own mechanisms separate from electrophilic reactions

But we use an acid in both the reactions, and the reaction is initiated by an H(with a slightly positive charge) atom attached to the acid. Will this, then, not be an electrophilic reaction?
Or is it that only addition/substitution reactions can be electrophilic or nucleophilic, and elimination can not be?
If so, reason please.
Cause we're still using an acid where the H atom can be considered as an electrophile.

In the syllabus it is written explain the terms bond energy, bond length and bond polarity and use them to compare the reactivities of covalent bonds.

My doubt is, what does bond polarity do to covalent bond, like how does it affect it?

bond polarity means what is the EN value difference of the bond . this will dictate bond strength and mp bp

High bond polarity= High bond energy= reduced bond length. This means the covalent bond is strong.
