Answer: Option (A) is the correct answer.
Explanation:
It is known that when sharing of electrons take place between two combining atoms then the bond formed is known as a covalent bond. In general, a covalent bond is formed between two non-metal atoms.
For example, the compound HCl has a covalent bond between the hydrogen and chlorine atom. As hydrogen atom has 1 valence electron and chlorine atom has 7 valence electrons.
So, in order to attain stability both these atoms will share their valence electrons and hence, a covalent bond is formed.
On the other hand, when an electron is transferred from one atom to another then it tends to form an ionic bond.
For example, the compound NaCl has an ionic bond.
Thus, we can conclude that when atomic orbitals of two nuclei overlap, the mutual attraction between a negatively charged electron pair and the two positively charged nuclei forms a covalent bond.
Answer:
It is an saturated compound since there are no c-c double or tripple bonds.
Explanation:
If we had such double or tripple bonds the remaining o &H atoms cannot be accommodated to the carbon chain.
the carbon skeleton has (26×2)+6=58 valence electrons
O occupies 2 for each
18×2= 36
,58-36=22
only 22H can be directly bonded to the carbon skeleton.
remaining H= 14
therefore 7carbonyl carbon atoms will have to turn into carbinol carbon atoms .
so no space for c-c double bonds
Answer:
V2 = 90.7 mL
Explanation:
pressure and volume are inversely proportional, if the pressure is increased, the volume will decrease. In an isothermal process:
p1V1 = p2V2
V2 = p1V1/p2 = (277 torr×187 mL)/571 torr
V2 = 90.7 mL
Answer : Option B) Dependent variable.
Explanation : In this experiment the growth of pea plants is a dependent variable because, it depends upon the light which is available to it. As in the experiment James took two pea plants, and placed one in a dark closet and the other on a sunny window sill. Both were located in air-conditioned rooms. But the growth of the plant differs because of the light availability to it. Therefore, it is a dependent variable.
