The elements corresponding to the given electronic configuration are to be identified; the identified elements are to be arranged in the increasing order of their electronegativity value. Concept introduction: The number of electrons can be obtained from the electronic configuration of an element. The number of electrons is equal to the atomic number of the element. The element can be identified using the atomic number. Electronegativity can be defined as the measure of the tendency of an atom to attract the shared pair of electrons towards itself. To determine: The element corresponding to the given electron configurations and the correct arrangement of these elements in the increasing order of electronegativity.

The total number of carbons in the parent chain is incorrect. Review the reaction conditions including starting materials and/or
intermediate structures and recount the number of carbon atoms in the parent chain of your structure.

Using a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40.
a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L)
b) Calculate the molar absorptivity, a, of the 1645 cm-1 band
c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c
d) Calculate x for the 1645 cm-1 band
Convert 1.38 eV into wavelength (nm) and wavenumber (cm-1) (c = 2.998 x 108 m/s; h = 6.626 x 10-34 J*s).
