The answer is simple, like you are hungry you can pay more to get the food than that of the person who is less hungry, Similarily here the non metals want electrons thus they spend the energy more , or they release the energy. By this they lose the energy. So smaller is the sizeContinue reading “The electrons that gain enthalpy for metals is positive and negative for non metals. Also, if metals are bigger in size than non metals then, how can electrons gain enthalpy is inversely proportional to the atomic size?”

Why the electron affinity or electron gain enthalpy of Chlorine is higher than Fluorine ? Even if Fluorine is most electronegative element.
chlorine shows exceptionally higher electron gain enthalpy than that of florine.

What are the Banana Bonds?
What is a ”three centre two electron bond”? These are the type of covalent bonds in which overlapping of orbitals of three atoms take place but sharing only two electrons. These type of bonds that are found in electron deficient molecules. for example in case of BF3 , the molecule exists as a dimer thatContinue reading “What are the Banana Bonds?”
Why CH3 group is Ortho and para directing in nature in Toulene ?
IN CASE OF TOLUENE the methyl group attached to the ring, increases the electron density at ortho and para positions by resonance without changing anything at the meta position. Thus the attacking reagent directly attacks at the electron rich site , thus the methyl group is ortho directing. you can easily understand the movement ofContinue reading “Why CH3 group is Ortho and para directing in nature in Toulene ?”
The second electron affinity of oxygen is positive, what does that mean?
Electron affinity is the amount of energy change during the addition of an electron to an isolated gaseous atom. It can be positive as well as negative. Negative electron affinity means that the energy is released during the addition of electron. Which is a favorable condition for gaining an electron. But positive value means thatContinue reading “The second electron affinity of oxygen is positive, what does that mean?”
