The number of unpaired electrons are present in given atoms have to be identified. Concept introduction: An orbital is an area of space in which electrons are orderly filled. The maximum capacity in any type of orbital is two electrons. An atomic orbital is defined as the region of space in which the probability of finding the electrons is highest. It is subdivided into four orbitals such as s , p , d a n d f orbitals which depend upon the number of electrons present in the nucleus of a particular atom. Aufbau principle: Electrons first occupy orbitals with lower energy than higher energy. An orbital can be occupied only by two electrons having opposite spins. Each electron fills each orbital till it is half filled. Greater the number of parallel spins of electrons more stable the orbital. This is known as Hund’s rule. The order of electrons filling in an atom is given as Figure 1 Pauli Exclusion Principle: It states that in an atom no two electrons have same quantum numbers. That is two electrons in an atom can have same three quantum number ( n, l, m l ) but the spin quantum number differs because of electrons in same orbital spins in opposite direction.

Interpretation Introduction

Interpretation:

The number of unpaired electrons are present in given atoms have to be identified.

Concept introduction:

An orbital is an area of space in which electrons are orderly filled. The maximum capacity in any type of orbital is two electrons. An atomic orbital is defined as the region of space in which the probability of finding the electrons is highest. It is subdivided into four orbitals such as s, p, d and f orbitals which depend upon the number of electrons present in the nucleus of a particular atom.

Aufbau principle:

Electrons first occupy orbitals with lower energy than higher energy.

An orbital can be occupied only by two electrons having opposite spins.

Each electron fills each orbital till it is half filled. Greater the number of parallel spins of electrons more stable the orbital. This is known as Hund’s rule.

The order of electrons filling in an atom is given as

Pauli Exclusion Principle:

It states that in an atom no two electrons have same quantum numbers. That is two electrons in an atom can have same three quantum number (n, l, ml) but the spin quantum number differs because of electrons in same orbital spins in opposite direction.

Write structural formulas for the major products by doing addition reactions 1. You must add H2 as Pt is catalyst it does not take part in reactions only speed up the process H₂ CH2=CH-CH3 Pt 2. Add HCI break it into H and Cl CH3 HCI 3. Add Br2 only CC14 is catalyst CH3-CH=CH2 B12 CCl4 4. Add water to this and draw major product, H2SO4 is catalyst you have add water H20 in both the reaction below H₂SO4 CH3-CH=CH2 CH3 H2SO4/H₂O CH3-C=CH2 reflux ?

Plan the synthesis of the following compound using the starting material provided and any other reagents needed as long as carbon based reagents have 3 carbons or less. Either the retrosynthesis or the forward synthesis (mechanisms are not required but will be graded if provided) will be accepted if all necessary reagents and intermediates are shown (solvents and temperature requirements are not needed unless specifically involved in the reaction, i.e. DMSO in the Swern oxidation or heat in the KMnO4 oxidation).
