I would be glad if someone compiled a list or atleast provide the link for the actions of various oxidizing and reducing agents like LAH, BAH, hydrogen, potassium permanganate etc. and on the various functional groups. This will be very useful to any organic aficionado and I will be very happy...

I didn't

Homework Statement Just refer to the figure. The part shown is a part of a big circuit which you and anybody else shouldn't worry about.Homework Equations The Attempt at a Solution I considered the battery terminals to be at 10 and 0V respectively. So the farther end of the resistor should be...

Homework Statement Are all the atoms except the hydrogens involved in electron delocalization in benzophenone? Homework Equations The Attempt at a Solution Yes as the double bonds are in conjugation. But we were told that the answer is no. Can anybody explain why this so?

Homework Statement Two rivers of unequal width (64m and 125m) meet at a right angle, forming an L-shaped channel. What is the longest possible log you can float on it? Homework Equations The Attempt at a Solution I tried for equal widths and built a recursive algorithm for turning...

Homework Statement Why is THF used as a solvent while preparing an alkyl magnesium bromide instead of diethyl ether?Homework Equations The Attempt at a Solution THF and diethyl ether being polar solvents are able to co-ordinate to the magnesium. May be it is because THF, which is more polar...

Homework Statement When an EM wave propagates, the E and M field at a point are perpendicular. If E and M at a point are NOT perpendicular to each other, can it be that an EM wave is passing through that point?Homework Equations The Attempt at a Solution Consider a linearly polarized light...

Jeff got it right. To what extent did it amuse you?

Follow the below four steps to amuse yourself 1) Take a semicircular wire. You know that its COM is at (0,2R/\pi). Now pass an axis through its COM and perpendicular to the line joining its ends. 2)Rotate this "half-lollipop" about the axis fixed till it comes to another position. The COM...

The real problem is that I am still in high school. In the book which I am reading, the results are stated without proof(except the criterion for minima). Andy was right. The author was referring to the diffraction pattern obtained at infinity.

The result obtained from integration and your symmetry argument are NOT the same. For a semicircular wire, the COM is (0, \frac{2R}{\pi}) while from integration, it is (0,0,R/2). Can anybody explain this?

The relation between the angles for which the minima occurs for a Fraunhofer diffraction(parallel rays, large separation between screen and slit) is derived by using the destructive interference criterion. Why isn't there any mention of the criterion for maxima? The results obtained from the...

Dihalocarbenes exist in singlet state. Wiki says that singlet carbenes can be stabilized by electron donating groups as they help in delocalizing the electrons into an empty p-orbital. So why is CF2 the most stable. It has been almost 48 hours since the last post. Why isn't anybody...

Homework Statement Predict the stability order of dihalocarbenes. Homework Equations The Attempt at a Solution I'm lost. Just give me a hint and I'll see if I can get it figured out.

Assuming dimethylcyclohexane exists always as a chair, what would the answer for 2),3) be? If you encounter any molecule whose mirror is nothing but the molecule which results after flipping(which you should assume to be an instantaneous process), then treat it as achiral. Though this might not...
