Could someone please help me??
1 answer:
Sum of ionisation energies is very high.
Let's check once .
Group 13 means boron family.
- Take example of Aluminium (Al)
- Atomic no 13
Electronic configuration is given by
Look at p orbital .
- It's half filled.
- So it's far stable than other group's elements except noble gases
Its first ionisation enthalpy is that much high that it needs a lots of energy to form ionic compounds by donating that.
- Second and third enthalpies becomes more and more high as it closes the nucleus.
So boron family is unable to form ionic compounds easily .
- So they prefer sharing electrons and forming covalent compounds

Answer:
CH3COCH3
Explanation:
Acetone is an organic compound belonging to the organic ketone function.
To recognize which function a compound belongs to, we must analyze its functional group. For example, hydroxyl (OH) is characteristic of alcohols. For ketones, the functional group is carbonyl, which is represented below.
Analyzing the options, we can notice that NH3, HNO3, KClO2 and H3PO3 are inorganic compunds, because they don't have carbon in their structures. KOH has the hydroxyl, so it's a alchol, and CH3COCH3 may be writing as a ketone.
