1)    ----- is the least electronegative element and ---- is the most electronegative element in the periodic table.

A) Caesium & Fluorine 

B) Beryllium & carbon 

C) Magnesium & Chloine 

D) Fluorine & Francium

Electronegativity decreases down a group and increases across a period. Alkali metals at the bottom-left are least electronegative, while halogens at the top-right are highly electronegative. Fluorine is the most electronegative (Pauling ≈ 3.98). The commonly accepted least electronegative element in textbooks is caesium (≈ 0.79); francium’s value is largely theoretical due to its rarity, so Cs is used.

Ans)  A) Caesium & Fluorine


2)   Which following body is associated with ‘Surety Bonds’ that protects the party involved in a transaction or contract from potential financial loss caused by the breach of contract or other types of non-performance?

A) Reserve Bank of India

B) Insurance Regulatory and Development Authority

C) Securities and Exchange Board of India

D) National Payments Corporation of India

A surety bond is an insurance product—a three-party contract (principal, obligee, surety) that guarantees performance/payment. In India, issuance and regulation of surety bonds fall under the Insurance Regulatory and Development Authority of India (IRDAI). RBI regulates banks, SEBI oversees the securities market, and NPCI handles retail payment systems; none of these regulate insurance products like surety bonds.

Ans) B) Insurance Regulatory and Development Authority
