In this post, we are going to study one of the most seminal concepts, not only in analytical but in entire chemistry. Understanding this concept
9.Confidence Limit (CL)- The confidence limit is the level of confidence we have about a value being statistically significant. Confidence Limit (CL)= 100 × (1 − α)
From this post onwards we will start getting acquainted with some fundamentals of analytical chemistry. What is analytical chemistry? What all topics does it encompass?
5) Is it cyclic ? ✓ Conjugated double bonds ? ✓ Is it planar? × # of π electrons 8 # of lone pair of
Q: Classify the following compounds as aromatic, anti-aromatic or non-aromatic – 1) Is it cyclic ? ✓ Conjugated double bonds ? ✓ Is it planar?
“There is no exception to the rule, that every rule has an exception.”- James Thurber. After learning all about aromaticity and antiaromaticity, we now proceed
Let us now begin to discuss the magnetic properties of aromatic compounds. 3]Magnetic properties. I) Aromatic ring current– Aromatic compounds have delocalised , closed loop
We have studied aromaticity in detail and are acquainted with various compounds that are aromatic. A variety of physical properties have been used as a
We have been reiterating that aromatic compounds have 4n+2π electrons and antiaromatic compounds 4n π electrons. Ever wondered why these numbers are so important? Let’s
We saw earlier that aromaticity refers to the extra stability that some cyclic compounds have, owing to their structure. Antiaromaticity means exactly the opposite of
Elemental carbon in its sp2 hybridized state can form some very interesting structures, which have very wide applications in industry. Fullerenes are one such class
Is annulene aromatic? annulene has 4n π electrons and so is anti-aromatic. It is highly unstable compound and exists only at very low temperatures. At
