The general layout of a modern periodic table has to be described. Concept Introduction: In the modern periodic table elements are arranged in order of increasing atomic number . It has been arranged as rows and column, arrangement of elements from left to right (row) as increasing atomic number called periods and arrangement of elements from top to bottom (column) in order of increasing atomic number called group. Elements in a period have the same number of atomic orbital; number of shells is the same as period number. Elements in the same group exhibit similar physical and chemical properties. To explain groups and periods of elements in the modern periodic table To explain: the classification of elements in the modern periodic table. To explain: the representation of an element on the periodic table.

Concept Introduction:

In the modern periodic table elements are arranged in order of increasing atomic number. It has been arranged as rows and column, arrangement of elements from left to right (row) as increasing atomic number called periods and arrangement of elements from top to bottom (column) in order of increasing atomic number called group. Elements in a period have the same number of atomic orbital; number of shells is the same as period number. Elements in the same group exhibit similar physical and chemical properties.

To explain groups and periods of elements in the modern periodic table

To explain: the classification of elements in the modern periodic table.

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).
