Class 11th

The Pauli exclusion principle states that no two electrons in an atom can have the same four quantum numbers. In other words, only two electrons may exist in the same atomic orbital, and these electrons must have opposite spins. (a) and (f) violate the Pauli exclusion principle. Hund's rule states that the most stable arrangement of electrons in subshells is the one with the greatest number of parallel spins. (b), (d) and (e) violate Hund's rule.

N₂O&NO   

Red phosphorus undergoes disproportionation on reaction with alkali to form H₄P₂O₆ and PH₃

Order of electronegativity sp carbon > sp² Carbon > sp³ carbon

1st order reaction is the fastest at the starting of the reaction then it decrease also you can see the slope which is equal to rate.

Assign R & S nomenclature to chiral carbons

Kindly consider the following figure

As bond order is increasing it implies bond strength is increasing. As bond order is increasing it implies bond strength is increasing.

Peroxyacetyl nitrate is a secondary air pollutant

$x^2+(y-1{)}^2=y^2$

$\Rightarrow x^2-2y+1+y^2=y^2\Rightarrow x^2=2y-1\Rightarrow x^2=2\left(y-\frac{1}{2}\right)$
