What is the expected product when acetaldehyde and hydrogen react in the presence of platinum

formation of alcohol or primary alcohol occur in this reaction. Reduction occurs when acetaldehyde react with hydrogen that is addition of hydrogen occur in acetaldehyde compound, the double bond between oxygen and carbon breaks down and addition of hydrogen with oxygen occur forming hydroxyl and also addition of hydrogen occur at carbon results in formation of alcohol.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
