Production of aromatic hydrocarbons (arenes) like benzene, toluene and xylenes. Earlier the bulk of arenes were obtained from coal tar, but now they are derived from petroleum by the process of reforming. Increasing the octane number of straight-run gasoline by increasing the proport..

In this representation one views the carbon-carbon bond directly end-on and represents the two carbon atoms by a circle. Lines going to the center of the circle represent substituents on the front carbon, and lines going to the edge of the circle represent substituents on the rear carbon. The adva..

The intersection of the horizontal and vertical lines represents the chiral center (the chiral carbon). The horizontal lines indicate bonds directed towards the reader. The vertical lines indicate bonds directed away from the reader. By rotating through an angle of 180 o within the plan..

The intersection of the horizontal and vertical lines represents the chiral center (the chiral carbon..

Theorem : - In any triangle ABC, with sides a = BC, b = CA and c = BA, then prove that a = b cos C + c cos B, b = c cos A + a cos C, c = a cos B + b cos A Fig (i) Fig (ii) Fig (i..

Horizontal range is give by This shows that there are two angles of projection for the same horizontal range i.e., J and (90 o - J ) with the horizontal. The projectile will cover the same horizontal range whether it is thrown at an angle (90 0 ..

In this representation one views the carbon-carbon bond from an oblique angle. The spatial orientation are indicated by employing heavy tapered lines for substituents coming out of the page, normal lines for substituents in the plane of the page, and dashed lines for substituents going back behind..

Nina is working on a project. She planned to spend 50 days on the project. After the project was completed, she figured out that she had taken 120% of the estimated time to complete the project. Find the number of days she spent on the project. => 1..

It takes 8 months for William to complete a project and 2 years to complete a second project. How many times as long does it take to complete the second project than the first one? => 2 or 6 or 1 or 3..

The total investment and the total revenue from four projects done by a company are represented in the bar graph. What is the total profit earned by the company from all the projects? => $60 mil or $160 mil or $100 mil or $50 mil..
