The C=O group gives a peak in the 13CNMR spectrum between 160-220 ppm.
The peak is typically observed between 160-220 ppm.
The exact chemical shift depends on the nature of the carbonyl group and its neighboring atoms.
The peak can be used to identify the presence of a carbonyl group in a molecule.
Examples of carbonyl-containing functional groups include ketones, aldehydes, carboxylic acids, and esters.
Presence of Br can be identified by observing a peak at m/z value corresponding to the isotope of Br.
Look for a peak at m/z value corresponding to the isotope of Br (79Br or 81Br)
Check for the presence of characteristic fragments such as [M-Br]+ or [M-2Br]+
Compare the mass spectra of the compound with and without Br to identify the difference
Use other spectroscopic techniques such as NMR to confirm the presence of Br
Nuclear Overhauser effect is a phenomenon in NMR spectroscopy where nuclear spins of different atoms interact with each other.
It is used to determine the distance between two atoms in a molecule.
It occurs due to the transfer of nuclear spin polarization from one nucleus to another.
It is more pronounced when the two nuclei are close in space.
It is commonly used in structural biology to study protein structures.
It can al...
The Grignard reaction involves the addition of an organomagnesium halide to a carbonyl group, resulting in the formation of a new carbon-carbon bond.
Named after French chemist Victor Grignard
Used to synthesize alcohols, carboxylic acids, and other compounds
Requires anhydrous conditions and a non-protic solvent
Example: Addition of phenylmagnesium bromide to formaldehyde results in the formation of benzyl alcohol

Pneumatic systems use compressed air to transmit power, while hydraulic systems use fluid to transmit power.
Pneumatic systems use air as the working fluid, while hydraulic systems use liquid.
Pneumatic systems are typically used for lighter loads and faster movements, while hydraulic systems are used for heavier loads and slower movements.
Pneumatic systems are generally less expensive and easier to maintain compared to ...
There are several types of welding techniques used in various industries.
Arc welding: Uses an electric arc to create heat and join metals.
MIG welding: Uses a consumable wire electrode and shielding gas to join metals.
TIG welding: Uses a non-consumable tungsten electrode and inert gas to join metals.
Spot welding: Joins metal sheets by applying pressure and heat at specific points.
Flux-cored arc welding: Similar to MIG w...
CNC and lathe machines are used for precision cutting and shaping of materials.
CNC machines use computer programming to control the cutting tools, allowing for highly precise and complex shapes to be created.
Lathe machines are used for turning and shaping cylindrical objects, such as metal rods or wooden dowels.
Both machines are commonly used in manufacturing and engineering industries.
Examples of products made using C...
UPLC stands for Ultra Performance Liquid Chromatography.
UPLC is a technique used in analytical chemistry to separate, identify, and quantify components in a mixture.
It is an advanced form of liquid chromatography that utilizes smaller particle sizes and higher pressures for faster and more efficient separations.
UPLC is commonly used in pharmaceutical, environmental, and food analysis.
It offers improved resolution, sens...
