Read the given passage and answer the question number 1 to 5 that follows: The halogens have the smallest atomic radii in their respective periods. The atomic radius of fluorine is extremely small. All halogens exhibit-1 oxidation state. They are strong oxidising agents and have maximum negative electron gain enthalpy. Among halogens, and ionisation enthalpy are higher for fluorine than expected whereas bond dissociation enthalpy, m.p and b.p and electron gain enthalpy are quite lower than expected. Halogens react with hydrogen to give hydrogen halides (HX) and combine amongst themselves to form a number of compounds of the type, XX',XX'_3,XX'_5 and XX'_7 called inter-halogens. Why flourine shows anomalous behaviour as compared to other halogens?

1.	Read the given passage and answer the question number 1 to 5 that follows: The halogens have the smallest atomic radii in their respective periods. The atomic radius of fluorine is extremely small. All halogens exhibit-1 oxidation state. They are strong oxidising agents and have maximum negative electron gain enthalpy. Among halogens, and ionisation enthalpy are higher for fluorine than expected whereas bond dissociation enthalpy, m.p and b.p and electron gain enthalpy are quite lower than expected. Halogens react with hydrogen to give hydrogen halides (HX) and combine amongst themselves to form a number of compounds of the type, XX',XX'_3,XX'_5 and XX'_7 called inter-halogens. Why flourine shows anomalous behaviour as compared to other halogens?
Answer» SOLUTION :This is due to small ATOMIC RADIUS and HIGH ELECTRON density.
