Only CH4 is covalently bonded. All other compounds are ionic compounds.
So A is the answer.
Hope it helps!
The element Bromine is known as the chemical symbol Br2
Answer:
c sounds like the most reasonable answer rember to always divide the pressure value by 101
Answer:
Correct option : B
Explanation:
First compare with
there are two lone pair in but only one lone pair presen in the so more lone pair means more repulsion and hence less bond bond angle beacuse of lone pair repulsion bonded atom come closer and hence bond angle decreased .
bond angle inversely proporional to repulsion so more repulsion means less bond angle
does no exist it exist only in the form of and here assuming because in case of difficult to compare bond angle because here two different type of bond angle is present.
there is no lone pair in the so here will no be any repulsion and hence bond will be more in as compared to
Answer:
Resonance
Explanation:
Resonance is an idea in chemistry that is used to explain such properties as equal bond lengths, bond angles and some other chemical behaviours. Resonance structures show the possible distribution of electrons in molecules. All the contributing canonical or resonance structures give a clue regarding the true structure of the chemical specie under consideration.
The true structure of the specie is somewhere in between that of all the contributing canonical structures. Resonance is often employed to explain properties such as equal bond lengths and bond angles just as typified in the question under consideration.
