(a)
Interpretation: Comprehend the Lewis dot structure of
Concept Introduction: The chemical compounds can be classified as covalent compound and ionic compound. Ionic compounds have complete negative and positive charges on it whereas covalent compounds are formed by equal sharing of electrons between bonded atoms.
The polarity of molecule depends on the presence of electropositive and electronegative atoms present in the molecule.
Due to electronegativity difference between bonded atoms, partial charges induce on the bonded atoms. The partial charges effect the physical properties of the polar molecules.

Because of the presence of partial charges on
Since it is a polar molecule therefore it will be soluble in polar solvents like water. Whereas it will be insoluble in non-polar solvents therefore it will make round drop on waxed paper as wax is a non-polar molecule.

To get the octet configuration, Br share one of its valence electron with H to form covalent bond and H also shares its electron to get duplet configuration that leads to formation of polar covalent bond in molecule.
Since it is a polar molecule therefore it will be soluble in polar solvents like water. Whereas it will be insoluble in non-polar solvents therefore it will make round drop on waxed paper as wax is a non-polar molecule.

- For Raman spectroscopy/imaging, which statement is not true regarding its disadvantages? a) Limited spatial resolution. b) Short integration time. c) A one-dimensional technique. d) Weak signal, only 1 in 108 incident photons is Raman scattered. e) Fluorescence interference.arrow_forwardUsing 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. (Please provide a full derivation of the equation for x from the equation for I). d) Calculate x for the 1645 cm-1 bandarrow_forwardI need help with the follloaingarrow_forward
- For a CARS experiment on a Raman band 918 cm-1, if omega1= 1280 nm, calculate the omega2 in wavelength (nm) and the CARS output in wavelength (nm).arrow_forwardI need help with the following questionarrow_forwardFor CARS, which statement is not true regarding its advantages? a) Contrast signal based on vibrational characteristics, no need for fluorescent tagging. b) Stronger signals than spontaneous Raman. c) Suffers from fluorescence interference, because CARS signal is at high frequency. d) Faster, more efficient imaging for real-time analysis. e) Higher resolution than spontaneous Raman microscopy.arrow_forward
