Oleic acid belongs to class of alkene and in alkenes, addition of
across
that is carbon carbon double bond results in the formation of alkane as a product in the presence of specific catalyst such as nickel, palladium and platinum. The reaction is said to be hydrogenation reaction.
Oleic acid (
) consist of 17 carbon atoms attached to 33 hydrogen atoms with one double bond between two carbon atoms and one carboxylic group i.e.(
). When oleic acid is hydrogenated or reacts with hydrogen in the presence of catalyst, then the carbon carbon double breaks by the addition
and alkane product i.e. stearic acid (
) is formed.
The chemical reaction is shown in the image.
Answer:
Br
Explanation:
Bromine atoms tend to gain just one electron to get to a full octet, as Bromine is in Group VII.
Ionic molecules have higher boiling point than covalent molecules.
So that leaves Na2SO4 and NaCl.
The ionic molecule with higher charge will have higher boiling point.
Na2SO4 have ions with charge +-2.
NaCl have ions with charge +-1.
So the answer is C.
(4) slate because it is the strongest
