Question

which of these statement is not true?
a)alkaline earth metals react with acid to liberate hydrogen
b)metals halides formed by alkaline earth metals are hygroscopic in nature
c)alkaline earth metals react readily with water
d)alkaline earth metals are less reactive than alkali metals

Answer 1

Alkaline earth metals react with water and release hydrogen.
Nitrates calcium, magnesium and other alkaline earth metal hygroscopic.
Alkaline earth metals react with water, but not as easily as alkali metals.
Alkaline earth metals are less reactive than the alkali metals.
So wrong statement is that "alkaline earth metals react easily with water"
Answer: с (alkaline earth metals react readily with water)
