Chemistry carries the highest scoring potential in JEE for anyone who keeps the three branches separate in revision. This set covers physical chemistry numericals, organic reaction mechanisms and named reactions, and inorganic chemistry including periodic trends, chemical bonding and coordination compounds. Organic questions show the mechanism arrow by arrow, so the reasoning transfers to reactions you have not seen before.
The standard reduction potential of H⁺/H₂ electrode is taken as 0.00 V because:
Answer: B
SHE (Standard Hydrogen Electrode) is the arbitrary reference against which all other reduction potentials are measured.
Q.27Easy
What is the effect of temperature on the conductivity of ionic solutions?
Answer: B
Conductivity increases with temperature because ionic mobility increases due to decreased viscosity of the medium.
Q.28Easy
The electrochemical series is based on which property?
Answer: B
The electrochemical series arranges elements in order of their standard reduction potentials, with more positive values indicating stronger oxidizing agents.
Q.29Easy
Which factor does NOT significantly affect the conductance of an electrolytic solution?
Answer: C
Color of a solution is a physical property unrelated to ionic conductance. Conductance depends on nature of solute, concentration, temperature, and solvent.
