Which of the following property increases with an increase in the atomic no. of Group 14 elements?
Atomic size
Ionisation potential
Metallic character
Stability of +2 oxidation state
SiCl4 is easily hydrolysed but CCl4 is not. This is because
Silicon is non-metallic
Bonding in SiCl4 is ionic
Silicon can form hydrogen bond but carbon can not
Silicon can expand its co-ordination number beyond four but carbon can no
In the Group 13 elements, the +1 oxidation state of thallium is more stable than +3 oxidation state, because of
Replusion effect
Inductive effect
Inert pair effect
Increasing atomic number
The elements of Group 14
Form M4+ ions
Form M4- and M4+ ions
Exhibit oxidation state of +4
Exhibit oxidation states of +4 and +2
Which of the following is not a characteristic of carbon?
Catenation
