Explaining Polarity Of Molecular Substances

Question 1

Explain the polarity of a molecular substance (1) non polar symmetrical

Answer 1

__Is a __ shape around its central __ atom. There are ___ bond dipoles between ___ and where ___ is the most electronegative
The bond dipoles are arranged symmetrical around the central and are of equal size, therefore their effect cancel, there is no molecular dipole and __ is non polar

Question 2

Explain the polarity of a molecular substance (2) polar, symmetrical , different sizes

Answer 2

__Is a __ shape around its central __ atom. There are ___ bond dipoles between ___ and where ___ is the most electronegative
The bond dipoles are arranged symmetrically around the central atom but are of different sizes, therefore their effect can’t cancel, there is a molecular dipole and is polar

Question 3

Explain the polarity of a molecular substance (3) polar, asymmetrical, different sizes

Answer 3

__Is a __ shape around its central __ atom. There are ___ bond dipoles between ___ and where ___ is the most electronegative
The bond dipoles are arranged asymmetrically around the central atom and are of different sizes, therefore their effect can’t cancel, there is a molecular dipole and ___ is polar
