Ethan Allen

(noun)

A farmer, businessman, land speculator, philosopher, writer, American Revolutionary War patriot, and politician; he is best known as one of the founders of the state of Vermont and for the capture of Fort Ticonderoga early in the American Revolutionary War.

Examples of Ethan Allen in the following topics:

  • Fort Ticonderoga

    • The capture of Fort Ticonderoga occurred in the early stages of the American Revolutionary War when a small force of Green Mountain Boys, led by Ethan Allen and Colonel Benedict Arnold, overcame a small British garrison at the fort and looted the personal belongings of the garrison.
    • Ethan Allen and other patriots in the disputed New Hampshire Grants territory also recognized the fort's value, as it played a role in the dispute over that area between New York and New Hampshire.
    • Arnold departed immediately after receiving his instructions and reached the border between Massachusetts and the Grants, where he learned of the recruitment efforts of the Connecticut Committee and that Ethan Allen and the Green Mountain Boys were already on their way north.
    • As dawn approached, Allen and Arnold became fearful of losing the element of surprise, so they decided to attack with the men at hand rather than wait for reinforcements.
    • An 1875 print by John Steeple Davis giving an idealized and inaccurate depiction of Ethan Allen demanding the fort's surrender.

  • Deism

    • Other notable Founding Fathers may have been more directly Deist, such as James Madison, Alexander Hamilton, Ethan Allen, and Thomas Paine.

  • Acidity of Terminal Alkynes

    • It is difficult to measure such weak acids, but estimates put the pKa of ethane at about 48.
    • Thus, the pKa of ethene is estimated at 44, and the pKa of ethyne (acetylene) is found to be 25, making it 1023 times stronger an acid than ethane.
    • However, if the weaker base KOH is used for the elimination, the terminal alkyne salt is not formed, or is formed reversibly, and the initially generated 1-pentyne rearranges to the more stable 2-pentyne via an allene intermediate.
    • The resulting allenic carbanions undergo rapid proton transfer equilibria, leading to the relatively stable terminal alkyne conjugate base.
    • The R and R' substituents on the allenic intermediate range from propyl to hydrogen, as the proton transfers proceed.

  • Ethane Conformations

    • The simple alkane ethane provides a good introduction to conformational analysis.
    • The first views the ethane molecule from the side, with the carbon-carbon bond being horizontal to the viewer.
    • Consequently, the potential energy associated with the various conformations of ethane varies with the dihedral angle of the bonds, as shown below.
    • Although the conformers of ethane are in rapid equilibrium with each other, the 3 kcal/mol energy difference leads to a substantial preponderance of staggered conformers (> 99.9%) at any given time.
    • Although steric and/or bond electron repulsion remain the most popular explanation for the hindered rotation of ethane, molecular orbital interactions have also been proposed as a significant factor.

  • Explanation of Summarizing

    • As with the other strategies, the teacher models the skill, then hands over the leadership responsibility to the students (Allen, 2003).

  • Butane Conformations

    • The hydrocarbon butane has a larger and more complex set of conformations associated with its constitution than does ethane.
    • As in the case of ethane, the staggered conformers are more stable than the eclipsed conformers by 2.8 to 4.5 kcal/mol.

  • sp3 Hybridization

    • The simplest of these is ethane (C2H6), in which an sp3 orbital on each of the two carbon atoms joins (overlaps) to form a carbon-carbon bond; then, the remaining carbon sp3 orbital overlaps with six hydrogen 1s orbitals to form the ethane molecule.

  • Challenges of Reciprocal Teaching

    • One challenge of using reciprocal teaching is that constructivists in the field of learning strategies do not agree on how it should be taught (Allen, 2003).
    • One way of teaching it is called "reciprocal teaching only", where the strategy is not introduced to the students prior to the group discussions (Allen, 2003).
    • The other way is called "explicit teaching before reciprocal teaching"; where students were introduced to the strategies before dialogue began (Allen, 2003).
