Question 5 Which of the following statements best contrasts a key difference between non polar and polar covalent bonds? A In a nonpolar bond electrons are shared equally.while in a polar bond, electrons are shared unequally. B In a nonpolar bond electrons are transferred, while in a polar bond, electrons are shared. C In a nonpolar bond electrons are shared unequally while in a polar bond, electrons are shared equally. D In a nonpolar bond electrons are shared, while in a polar bond, electrons are transferred.

## Step 1<br />The problem is asking us to identify the statement that best contrasts the key difference between nonpolar and polar covalent bonds. <br /><br />## Step 2<br />In a nonpolar covalent bond, the electrons are shared equally between the two atoms. This is because the two atoms have similar electronegativities, meaning they have a similar attraction for the electrons. <br /><br />## Step 3<br />On the other hand, in a polar covalent bond, the electrons are shared unequally. This is because the two atoms have different electronegativities, meaning one atom has a stronger attraction for the electrons than the other. <br /><br />## Step 4<br />Looking at the options, option A correctly states that in a nonpolar bond, electrons are shared equally, while in a polar bond, electrons are shared unequally. This is the correct contrast between nonpolar and polar covalent bonds.
