Answer:
The correct answer is - n and l.
Explanation:
The size of an orbital is determined by the principal number of shell which is represented by n. The larger the energy level (n) bigger the size of the orbital. N can be any integer value: 1, 2, 3 . . . . and so on.
l represents the angular momentum or subshell number provides the overall shape of an orbital in this subshell only integer values between 0 and n-1 are permitted.
Thus, n & l are two quantum numbers that determine the energy level of an orbital in a multielectron atom.
Answer:
Conjugate base of naphthol is highly stable but conjugate base of ethanol is unstable.
Explanation:
Naphthol gives acid base reaction with NaOH where naphthol acts as an acid and NaOH as a base.
Reactivity of naphthol towards NaOH is quite high because the conjugate base of naphthol is highly stable. Stability of the conjugate base arises due to delocalization of negative charge on oxygen atom into aromatic naphthalene ring.
Ethanol is not so reactive towards NaOH because the ethoxide ion is highly unstable due to lack of delocalization of negative charge on oxygen atom.
Resonance structures of conjugate base of naphthol has been shown below.
Answer:
Flatulence
Explanation:
In science, scientists often refer to gas as flatulence.
It's answer is c. N2
The maximum bond energy is of N2 because N2 molecule is formed by 3 covalent bonds and O2 molecule is formed by 2 covalent bonds.
Hope it helps :)
