Hydrogen in respect to chlorine, is :
electropositive
electronegative
neutral
none of the above
B.
electronegative
Chlorine is more electronegative (electronegativity = 3.0) than hydrogen (2.1). Hence, hydrogen is electropositive in respect to chlorine.
The compound insoluble in water is
mercurous nitrate
mercuric nitrate
mercurous chloride
mercurous perchlorate.
How does the ionisation energy of 1st group elements vary ?
Increases down the group
Decreases down the group
Remains unchanged
Variation is not regular
Dominance of strong repulsive forces among the molecules of the gas (Z = compressibility factor)
depends on Z and indicated by Z = 1
depends on Z and indicated by Z > 1
depends on Z and indicated by Z < 1
is independent of Z.
