A weak bond called a ______ bond results from an attraction between a slightly positive region in a molecule and a slightly nega
tamaranim1 [39]

<u>Answer:</u> The weak bond having slightly positive region and a slightly negative region is polar covalent bond.

<u>Explanation:</u>

Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms. <u>For Example:</u> HCl, CH_4 etc..

They are of two types:

  • <u>Polar covalent bond:</u> This bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond.

In this bond, a dipole is created. More electropnegative atom will have a slight negative charge and less electronegative atom will have a slight positive charge. For Example: CO_2,NO_2 etc..

  • <u>Non-polar covalent bond:</u> This bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: N_2,O_2 etc..

Hence, the weak bond having slightly positive region and a slightly negative region is polar covalent bond.

Only 11% of all the energy used in the US comes from a renewable source. Why is this a<br> problem?
mr Goodwill [35]
Fossil fuels and unnatural energy sources still dominate in the US, this influences many problems including global warming, climate change, and pollution. Burning fossil fuels is also a problem to human health. And unnatural resources won’t be there forever whereas, renewable sources could last a long time.
