Chemistry (iit jee) Exam 2025/2026 With 100% Correct Answers

Chemistry (iit jee) Exam 2025/2026
With 100% Correct Answers


Nonpolar covalent bond CORRECT ANSWERS when atoms in
the bond pull equally; Electronegativity difference of less than
0.5


Polar covalent bond CORRECT ANSWERS when atoms in the
bond pull unequally (polar bond); Electronegativity difference
from 0.5-1.6


Ionic bond CORRECT ANSWERS electronegativity difference
of more than 1.6


Assumptions for bonds CORRECT ANSWERS identical atoms
or CH-->nonpolar
nonmetal+nonmetal-->polar
metal+nonmetal-->ionic


Electron pull CORRECT ANSWERS the more electronegative
atom attracts electrons more strongly and gains a slightly
negative charge. The less electronegative atom has a slightly
positive charge.

, Polar molecules CORRECT ANSWERS one end of the
molecule is slightly negative and the other end is slightly
positive


Dipole CORRECT ANSWERS A molecule that has two poles
(dipolar molecule)


Network solids CORRECT ANSWERS solids in which all of
the atoms are covalently bonded to each other; Melting a
network solid would require breaking covalent bonds throughout
the solid


Linear CORRECT ANSWERS 2 atoms OR 1 center and 2
bonded
180º


VSEPR theory (aka valence-shell electron-pair repulsion theory)
CORRECT ANSWERS explains three dimensional shape; the
repulsion between electron pairs causes molecular shapes to
adjust so that the valence-electron pairs stay as far apart as
possible.


Tetrahedral CORRECT ANSWERS 1 center and 4 bonded
109.5º
