Well, the left half of allene is perpendicular to the right half. In order for a molecule to be planar, the whole molecule has to be planar. A simplified explanation is thatthe central carbon atom's px and py o

There are three different substances that contain a carbon-carbon double bond and have the formula C_4H_8. Draw them, and tell how they differ. A carbon-oxygen double bond is shorter than a carbon-oxygen single bond, yet all C-O bonds are experimentally deter...
Which statement about carbon bonds is correct? a) Carbon has very high electronegativity and therefore can form strong bonds. b) Carbon can make up to three types of bonds with any of the elements in the periodic table. c) Carbon can make both ionic and c ...

where C is carbon, H is hydrogen, O is oxygen, the hyphen is a single chemical bond between the atoms and the || symbol is a double bond between the atoms. For clarity, the bonds of the three hydrogen atoms to the left carbon atom are not shown. When ethanol is oxidized to acetic...
To achieve the sustainable development goals, we need to initiate green projects through green financial bonds, green banks, carbon market tools, other new financial instruments and new policies, fiscal policy, a green central bank, fintech, community-based green funds, and expand the financing of...
59 These were proposed to promote a proton to the aldehyde to facilitate nucleophilic attack of the amine to the carbonyl carbon. Both sulfated materials showed lower yields if solvents were used. The impact on the yield was diverse: while sulfated meglumine gave 97% yield in a model reaction...
