Answer:

I interpret the answers as being nonmetallic and metallic.

Explanation:

Nonmetals are in groups 14 - 18. Electronegativity is referred to as the want to attract electrons to an atom. Noble gases (group 18) have eight valence electrons in their outer subshells and are therefore atomically stable. Elements with only 7 valence electrons are very electronegative because they desire to obtain an electron to reach stability more than a group 2 element would (they are more likely to drop electrons by giving away in order to reach atomic stability of a group 18 element). This coincides with electron configuration, which is a very lengthy topic to cover. You can conduct more research if you would need it.

Classify methanal according to the position of the c=o group

seraphim [82]

Answer : Methanal also known as Formaldehyde $CH_{2}O$ is a chemical Aldehyde which contain ( -CHO) group.

Explanation :

In organic chemistry, a carbonyl group is a functional group which contain a carbon atom double-bonded to an oxygen atom i.e, ( C=O).

If carbonyl group is present in a compound then it can be a carboxylic (RCOOH), aldehyde (RCHO), ketone (RCOR'), ester ((RCOOR') or amide (RCONR'R") group.

Here are some functional groups naming according to the<em> IUPAC</em> rules and image also attached,

Carboxylic acid → (RCOOH) → ( name end in 'OIC ACID' )

Aldehyde → (RCOH) → ( name end in 'AL' )

Ketone → (RCOR') → ( name end in 'ONE' )

Ester → (RCOOR') → ( name end in 'ATE' )

Amide → (RCONR'R") → ( name end in 'AMIDE' )

In an aldehyde, atleast one hydrogen atom must be attached to the carbonyl carbon. For an aldehyde, remove ( -e) from alkane name and add ( -al) at the end of the compound.

Methanal is the IUPAC name for Formaldehyde.
