Question

The most chemically reactive metal elements are the alkali metals. They react
spontaneously with water or other substances in the atmosphere and must be stored under oil.
a. What type of reactions will these metals undergo?
b. Explain why these metals are so reactive in the type of reactions from part a.

Answer 1

I assume you are thinking of "synthesis" for a but a question like this can have so many different meanings. But I'll go with synthesis type reactions such as
Na + O2 ==> Na2O2--synthesis.
BUT Na + H2O ==> H2 + NaOH--single replacement. You figure it out.

They react this way because of the electron sructure.

Answer 2

a)F
b)Cl
c)COOCH3
d)H
e)CH2CH3
