Four stereoisomers exist for 4-chloro-2-pentene. Draw the structure of the isomer that has the E configuration around the double bond and the R configuration at the chiral center.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

elements make up everything, and they combine to make compounds.

the answer is c
