Why does phosphorus form P4 exists but P2 do not exists?
The P2 molecule of phosphorus is not found because of the larger size of the phosphorus atom. The phosphorus is so larger that the p-orbitals which are required to overlapp […]
What are the Characteristics of a lone pair ?
What are the characteristics of a lone pair? Characteristics of a lone pair Lone pair are the pair of electrons that do not take part in any chemical bond. They affect the symmetry of molecule or the shape of molecule as they interfere with the other electrons of the molecule . The electrons of lone pair repel the other bond […]
Bond angles of PF3 and PCl3
In case of PF3 the size of F is small and thus it approaches near to the central atom that is P. as it approaches near to P there comes the repulsion between the bond pairs, which widens the bond angle and makes it larger than in case of PCl3. Here two types of forces are deployed Bond pair – […]
What is the surface tension?
At surface of a liquid will their will be no forces (forces by molecules) acting on molecules in opposite directions such that the net force between molecules (only at surface) […]
Why are ion-dipole attractions stronger than dipole-dipole attractions?
See the ion is a proper charged particle, but dipole is a neutral olecule which is having polarity in it . the dipole is having temporary charge where as the […]
What is the hybridisation of Cl2? Is it different from the hybridisation of F2 molecules?
Here you can see the hybridization of both is same , both of these two elements have seven electrons in outermost shell and below is the diagram showing the electrons filled in s-subshell and p-subshell . one orbital of s- subshell and three orbitals of p-subshell are used during hybridisation. So the type of hybridization is sp3 hybridisation. Contribute freely […]
Why methanoic acid is stronger than ethanoic acid?
In case of methanoic acid the carbon atom joined to the carboxyl group is attached to only hydrogen atoms which are not able to increase the electron density. HCOOH But […]
What is a chemical bond ?
Chemical bond may be defined as the force of attraction by which two atoms are held together. The chemical bonds lead to the formation of molecules and crystals. There are […]
Full explanation of mole concept.
The word mole means pile up . This concept originated from a simple problem that was faced by the scientists to calculate the reactions. they needed a concept that could […]
How to find a lone pair in simple way?
Step 1: write the configuration of element and then show the valence elactrons around the symbol of element . Step2: make the bonds around the atom according to its valency […]
