Question

Complete for a thumbs up!

a. Explain resonance. Use images to help defend your explanation.

b. Create a table listing the trends on the periodic table of increasing atomic radius, electronegativity, and polarity.

c. Rank these compounds in order of least polar to most polar: CH₄, H₂O, HCl, and NO₂.

d. Draw the Lewis dot structures for CH₄, H₂O, HCl, and NO₂.

Answer 1

@ Sometimes all the properties of certain molecules are explained by a single structure. The Phenomenon of exhibiting more than one possible streecture is called as resonance Example. The resonance can be explained clearly on the basis of structure of benzene. The benzene can be represented following two canonical form. Autobro resonang Atomic Electro radius -negativity - Peridic table increases decreases t hat Atomic Radiles decreases Elechonegativity increases → increase in Ele ilecto negativ Bond Potarity increases with tivity Atomic Radices Electronegativity Decreases across the Period whereas increases down the group Increases across the Period whereas decreases down the and Polarity

CHA molecule, Non polar Polar molecule as bond dipole is not Zero and due to geometry seech that bond dipole don't Cancel each other. Hd NO2 Polar molecule due to high change It is a Polar molecule as the geometry is bent in electronegativity in the molecule so bond between these two dipole don't cancel each other atoms Rank will be , CHA < H20 L NO 2 LH-ct Leart (Most Polar) (Herre Non-Petar) CHa lewis dot structure H2O Lewis dot streecture Polar Hoocoot NO2 Lewid dot estreecte re Hice Lewis dot streecture Hood: H- & ÖSNÖ. ® ON
