Molecular formula: C 2 H 4 Structur..Structure of Ethene (Ethylene)
Ethylene is unique in that it is the only gaseous phytohormone. It is usually present in a minute quantity of about 0.1 ppm and causes marked physiological effects. Some of the inhibitory effects earlier attributed to auxin are now known to be caused by ethylene. High concentrations of auxins promo..
Mode of collection
Ethene gas formed is collected by the downward displacement of wate..
Addition or chain polymerization
Polymerization involves addition reactions. Example: Ethene polymerizes to form polythe..
Physical properties
Ethene is a colourless gas with a sweetish odour. It is insoluble in water and soluble in organic solvents. It causes unconsciousness when inhale..

The monomer molecules add together to make polymer molecules. Nothing in the monomer molecule is left out. Addition polymers are made from monomers that have a double bond between carbon atoms. These monomer molecules are generally alkenes such as ethene. Polystyr..

Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
It is a really good tutoring. The tutors are thoughtful, helpful, active to help students. A lot of ideas they have. Encouraging students too. -Riley
I learned a lot with this tutor. she was great at explaining the basic of chemistry. I have no questions left for the day. But I have lot to know from my tutor
Explained things very well and made them easy to understand
