As a central atom, sulfur can take more than eight electrons in its valence shell.
2 answers:
Sulphur is located in the third period and group 16. The general electronic configuration of group 16 is therefore the maximum number of valency electrons in group 16 is 6. The electronic configuration of sulphur is [Ne]
. Sulphur has six valency electrons whereas sulphur can have more than eight electrons in its valency shell as it have an empty d-shell electrons can accumulate in the empty d-shell. The complete d-shell and the
orbital will be empty. As each orbital can accept 2 electrons, sulphur can have 12 valency electrons in its valency shell.

Answer:
Option (4) is correct
Explanation:
- NaCl is an ionic solid.
and
ions are held together by strong coloumbic attractive force. Hence NaCl has highest boiling point'
- Ar is a monoatomic molecule. Hence only weak london dispersion force exists between Ar atom/molecules. Hence it requires lowest amount of energy to boil and thereby possess lowest boiling point.
and
are polar protic molecules. Hence they possess london dispersion force, dipole-dipole force and hydrogen bonding as intermolecular forces.
- Dipole-dipole force is stronger in
Hence order of boiling point :

Temperature of thermometer increases during the reaction, that means it receives heat. henceforth we can conclude that energy is released during the reaction that cleary mean that it's an Exothermic Reaction.
