| וד Using the above table of electronegatives, classify the C-O bond in carbon dioxide as either pure covalent, polar covalent or ionic. (Electronegativity
difference, AEN > 1.7 = ionic, AEN 0.4-1.7 = polar covalent, and AEN<0.4 = nonpolar covalent).
A) ionic
b)polar covalent
c)nonpolar covalent

i think its 5049.

i hope this !

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
